The human hand is made up of the wrist palm and fingers and consists of 27 bones 27 joints 34 muscles over 100 ligaments and tendons and many blood vessels and nerves.

Hand anatomy muscles palm. The palm volar which is the central region of the anterior part of the hand located superficially to the metacarpus the skin in this area contains dermal papillae to increase friction such as are also present on the fingers and used for fingerprints. The intrinsic muscles guide the fine motions of the fingers by getting the fingers positioned and holding them steady during hand activities.

Approximately14 percent of the population do not have this tendon but its. These include the adductor pollicis palmaris brevis interossei lumbricals thenar and hypothenar muscles.

The palmar interossei pull our fingers together. Also known as the broad palm or metacarpus it consists of the area between the five phalanges finger bones and the carpus wrist joint.

Areas of the human hand include. There are four dorsal and three palmar interossei muscles.

Two muscles allow the thumb to move across the palm of the hand an important function called thumb opposition. Adductor pollicis rotation.

The opisthenar area dorsal is the corresponding area on the posterior part of the hand. Injuries to the hand are a common cause of pain and other types of discomfort particularly in people who regularly use heavy equipment play sports.

Flexor pollicis longus and brevis and opponens pollicis extension. The intrinsic muscles of the hand are located within the hand itself.

The hands enable us to perform many of our daily activities such as driving writing and cooking. Overusing the hand can cause pain in the palm.

Abductor pollicis longus and brevis adduction. The following movements are possible.

Movements of the thumb anatomical position of the thumb the thumd become at a right angle with the palm of the hand and with the other fingers movements. They are responsible for the fine motor functions of the hand.

Hand muscles interossei dorsal and palmar the interossei muscles begin between the bones of the hand. While all interossei bend the mcp joints the dorsal interossei allow us to spread our fingers away from each other.

Extensor pollicis longus and brevis flexion and extension occur at the metacarpophalangeal joint abduction. In this article we shall be looking at the anatomy of the intrinsic muscles of the hand.
